Glass ink-jet printing ink

Abstract

The invention discloses a glass ink-jet printing ink. The ink comprises, by weight, 20-60% of inorganic colored frits, 35-65% of an organic solvent, 1-15% of a dispersing agent and 0.1-4.5 % of an antistatic agent, and all the components account for 100%. The inorganic colored frits comprise, by weight, 35-65% of Bi2O3, 10-40% of SiO2, 5-18% of B2O3, 1-5% of ZrO, 0.7-8% of Al2O3, 0.3-2.5% of K2O, 1-28% of a glass color former and 0.1-3% of a frit stabilizing agent. The frit stabilizing agent is selected from any one of vanadium pentoxide, sodium dihydrogen phosphate, sodium selenite, ammonium dihydrogen phosphate and sodium antimonite. The glass ink-jet printing ink is stable in quality, printed patterns are accurate, uniform and bright in color, the finished product is attractive, and the glass ink-jet printing ink has the good weather resistance and chemical-resistance stability.

Description

Technical field

[0001] The present invention involves the field of glass decoration, which specifically involves a glass inkjet printing ink. Background technique

[0002] Printing patterns on glass surface is a common way of decorative glass.At present, in China, the screen printing method is generally printed on the glass surface to achieve the decorative effect.However, the surface of the pattern obtained through the screen is rough, the color is monotonous, and the lines are rigid, and the effect is not ideal.In addition, the operation of the screen printing is more complicated, and it requires large manpower investment. The waste produced by printing also causes a certain degree of pollution to the environment.

[0003] In the past ten years, inkjet printing has appeared abroad, and the digital patterns in the computer are printed on the glass surface through the sprinkler's non -contact type.This technology uses a dedicated printing device to print the ink ink ink that can ...
